The staff of a test kitchen is attempting to determine the baking time, $ y $, of a roast, i.e., the time it takes the internal temperature of the roast to reach $ 165^{\circ} \mathrm{F} $, using two variables, the temperature setting of the oven, $ x_{1} $, and the weight of the roast, $ x_{2} $, in pounds. The data for 24 roasts are shown below.

$\text { Baking Times of Roasts }$

a. $\text { Fit a complete second-order model to the data. }$
b. Do the data provide sufficient evidence to indicate that the second-order terms contribute information for the prediction of $ y $ ? State the null and alternative hypothes
